Ezhucnul, Blind Eternal

Flying, phasing
When Ezhucnul, Blind Eternal phases out,
search your library for a colorless card, exile it,
then shuffle your library.
You may play colorless cards in exile.
If a permanent card is cast from exile, each other permanent with converted mana cost less than or
equal to that cards converted mana cost loses all abilities and becomes a colorless Wastes land
until end of turn.
